' SOFA-BED.

Be'it'known tha't'I, PErnR'E. KROEHLER,

*aj citizenof the United States, residing at Ndperville, in. the county-of Dupage and stateof'lllinois, have invented a Sofa-Bed,

of which the following is a Specification.

This. invention is. an improvement in sofa-- 'beds, and relates; more especially to a com-' bfination davenport and bed,

.Theprimary object of the invention is the "production ofa device of this character of such, construction. that when arranged to form a sofa or davenport there will be nothing i1 1.i-ts' appearance to indicate that it .IS convertlble into a bed, and when arranged intheform of a bed afwide mattress is brought into position and firmly supported for use, wlth. the upholstered seat of the vsofa or davenport turneddown and located under the front portion of the mattress so as to'beout of the wayiand protected during .the'use of the device as a' bed. i wlththis'principa'l object in-view .the in- '.Vention consists in the particular construc- 25..

thedcombination daven ort and bed; all as tion and arrangement of parts constituting hereinafter fully descrlbed and'specificall-y set' forth in the appended claims.

"In the accom anying drawings, which form a artoft isspecification: Figure 1 iszanen "view of a sofa-bed or combination davenport and bed, constructed in accordgance with my) present invention, the parts being arranged in bed form and the near fend of-the'sofa or davenport partly broken away to show the operating devices. Fig.2 is a similar view, w1th the parts arranged in bedform. Fig. 3 is a similar view, illus-- trating the operation of the partsin convert ing'the device from one formjto the'other.

Like numerals of reference indicate like parts in all the figures of the drawings.-

1 the firstanstancean ordinary formof sofa frame or dav'enport 'frame, comprising the end pieces 5, 5, upholstered back 6, and front rail 7, the end pieces and front rail beingconnected ,by front; corner-posts 8, as is usual; This frame may be made up in any suitable design, the box-like base bemg 1ntended to support the upholstered seatof the' sofa or davenportand receive 'the mattress sections, the latter being adapted to be but also may swing laterallya such manner as to swing into and out of the same, and in the present instance the swingmg connection 1s by .means of'a pair ofopposite links 10, which are pivoted at their lower ends, as at 11, to the upholstered seat at whatare normally the front corners there-- of, and .at their upper ends by the pivot pins 12 to the corner-posts 8.of the'sofa frame, whereby said seat is not only permitted a free plvotal movement upon'the ivots 11,

tance. As will be seen, therefore, t is particular form of link connectionallows the upholstered seat to be disposed inan inverted horizontal position in/front of the sofa-framewhen swungout of the same, and

stored seat 9 is supported in the frame in. I

to be located entirely within said frame when arranged to form the seat of the sofa or dav'enport." This "form, of connection possesses advantages over the ordinary hinge, usually employed, as it is stronger, more durable, and is invisible. v

Secured near the ends of the upholstered seat and projecting beyond and-at right angles to the inner side thereof are stand ar s or supporting-bars'13, to the outer ends of which .1s medially pivoted the center section 14 of the mattress frame, the. latter comprising saidcenter section and opposite end sections 15 and 16 pivoted thereto. The front mattress-frame section 15 may .be connected by links 17 to the'free end of the upholstered seat, while the rear mattr'essframe section 16 is connected to a pair of plvotally mounted in slotted plates 19 attached to the'inner sidesof'the end pieces of the sofa frame. The pivotal connections between the bell-crank levers and plates are by means of pins orstuds 18 en aging in. geates. By

pivoted to the aforesaid plates, and that the angles of said bell-crank lovers are loosely connected to rods '20 extending from the standards or supportingbars "13. The bell crank levers serve to properly supportthe rear mattressframe section in both its ele 'vated' and lowered pos1t1ons,-and the consupporting bell-crank levers -18 preferably V supporting-leg :21 at each end of said seat,

- and backward as it is raised and-lowered.

For the-purpose of supporting the outer or free end of the upholstered seat when the device is arranged in bed form I pivot a and. connect that end -of the leg that projects above the seat to a link 22 extending from the front mattress-frame section 15, so that whensaid mattress-frame section moves toward the upholstered seat as the latter is swung into the sofa frame it will operate through the medium of the links to close the legs alongside of the seat, thus concealing the legs when the, device is in sofa form as illustrated in Fig. 2.

The operation of converting the device from a sofa or davenport to a bed, and vice versa, will be readily understood from the drawings, in connection with the foregoing description, and it will be noted that when the device is in its normal condition, or sofa form, the end sections of the mattress frame will be disposed horizontally one above the other beneath the upholstered seat with the center section disposed vertically immediately in the rear of the front rail of the sofa, and that when the upholstered seat is swung out of the frame to an inverted horizontal position infront of the railthe mattress sections will be firmly supported at the center by the standards or bars 13, at the outer or front end by the links 17 extending from the. sofa seat, and at the T to 'inner or rear end by the bell-crank levers 18; theupholstered seat which supports the center and front mattress frame sections being supported at its inner end by the suspensi on-links 10, and at its outer end by the supportingdegs.

In order-to assist in the operation of opening the device into bed form I may provide a lifting-spring 23, connected at one end to the rear mattress-frame section and at itsother end to an eye-plate 24: attached to the inner side of the rear corner-post of the sofa-frame.

Having thus described my invention, what -I claim as new and desire to secure by Lettors-Patent, 1st
